Pile head breaking auxiliary device for cast-in-place pile and pile head breaking method
The invention discloses a pile head breaking auxiliary device for a cast-in-place pile and a pile head breaking method.The auxiliary device is installed at the top of a reinforcement cage and comprises a first annular partition plate provided with a first through hole, a second annular partition plate provided with a second through hole and a third through hole and a sleeve assembly. Wherein the first through hole corresponds to the second through hole; a first sleeve with two unclosed ends is communicated with the first through hole and the second through hole, and a second sleeve with one unclosed end is communicated with the first sleeve through the second through hole; a rubber air bag is arranged in the sleeve assembly; in addition, a hydraulic rod is further included, penetrates through the third through hole and is fixed to the top end of the first annular partition plate. During construction, a top main reinforcement of a reinforcement cage penetrates through the first through hole and the second through hole and is arranged in the first sleeve and the second sleeve in a sleeving manner, so that the device is mounted. By the adoption of the auxiliary device, bond wrapping between concrete and the top main reinforcement can be avoided; the flatness of the broken section of the pile head can be ensured by using the hydraulic rod; the rubber air bag and the hydraulic rod piece can be detached and recycled.
本发明公开了一种灌注桩用破除桩头辅助装置及破除桩头方法，该辅助装置安装于钢筋笼顶部，其包括设有第一通孔的第一环形隔板、设有第二通孔和第三通孔的第二环形隔板、以及套管组件。其中，第一通孔与第二通孔对应；两端不封闭的第一套管连通第一通孔和第二通孔，一端不封闭的第二套管通过第二通孔与第一套管连通；套管组件内部设有橡胶气囊；此外，还包括液压杆，其穿过第三通孔并固定于第一环形隔板顶端。施工时将钢筋笼的顶部主筋穿过第一通孔和第二通孔，并套设于第一套管和第二套管内，以实现该装置的安装。采用上述辅助装置，能够避免混凝土与顶部主筋发生握裹；液压杆的使用能够保证桩头破断面的平整度；橡胶气囊及液压杆件能够拆卸和回收。
